change-impact-analysis

change-impact-analysis is a skill for Claude Code, Codex from fzfclee/consulting-skills. It costs 49 tokens per session (787 once invoked), scanned A, original, Apache-2.0.

A consulting method for understanding how a planned change will affect different groups, processes, systems, locations, and schedules. It compares current and future ways of working.

In plain words
What is it for?
Use it when changing a process, system, organization, policy, or operating model. It helps produce a structured diagnosis and an action plan for adoption.
Why use it?
It shows who must adapt, how serious the impact is, what skills or preparation are missing, and where resistance may arise. Missing information is recorded as an assumption with a follow-up check.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

change-impact-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Change Impact Analysis

Use this skill to run Change Impact Analysis as a practical consulting method, not as a generic framework explanation.

Method Notes

  • Describe current-to-future behavior changes by affected group.
  • Assess impact severity, readiness, capability gap, and resistance.

Required Inputs

Collect or infer these inputs before execution:

  • change description
  • affected groups
  • current vs future process
  • adoption constraints

If an input is missing, do not block automatically. Mark it as missing, state the assumption used, and add a validation action.

When Not To Use

Do not use before the proposed change, affected groups, processes, systems, locations, and timing are defined. It identifies what must adapt; it does not replace a delivery plan or risk assessment.

Adjacent Methods

  • force-field-analysis: compare forces supporting and resisting a defined change.
  • raci-matrix: assign responsibility after the work and decisions are clear.
  • communications-plan: design audience messages, channels, cadence, and feedback.

Step-by-Step Execution

Step Required input How to execute Output
Define change Current state, future state, go-live date. State what will change in work, decisions, tools, or incentives. Change definition.
Identify affected groups Teams, roles, customers, partners, stakeholders. List who is affected and how. Affected group map.
Assess impact Current/future workflows, workload, capability, readiness. Rate impact severity, readiness, resistance, and capability gap. Impact assessment.
Design support Impact assessment. Define communication, training, sponsor, process, system, or policy support. Adoption support plan.
Plan rollout controls Support plan, timing, risks. Set owner, cadence, feedback loop, and escalation path. Change rollout plan.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
